Patented Apr. 29, 1930 UNITED STATES VICTOR I. PEARSON, F HECLA, SOUTH DAKOTA ANTENNA Application filed October 8, 1927. Serial No, 224,794.

The object of the invention is to provide an antenna to replace the usual wire strands employed for this purpose and which will materially reduce the introduction of static disturbances into the set with which it is connected; to provide an antenna adapted for mounting on the roof of a house without presenting an ungainly appearance and which will have the advantages of the conventional directional antenna; and to provide a device of this character which may be easily and cheaply made and therefore marketed at a low price.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings,

wherein:

Figure 1 is a perspective View of the invention.

Figures 2 and 3 are respectively sectional views on the planes indicated by the lines 2-2 and 83 of Figure 1.

The antenna is in the form of a closed hollow cylinder 10 mounted adjacent the upper extremity of a staff 11 which extends axially through the cylinder, the upper extremity 12 projecting beyond the upper end of the cylinder. The lower end of the staff is received in a post 14 which is mounted vertically on the roof 15 and retained in the proper position by braces 16 and 17.

At an intermediate point in its height, the cylinder is bounded by a ring 18 in the form of a wire strand, and spaced uniformly around this ring are the radial fingers 19, certain of the fingers such as those indicated at 19 being extensions of diametrical rods 20 extending through the cylindrical wall of the cylinder and crossing each other at the axis of the cylinder at which point they are united as well as connected to the staff 11 as indicated at 21. The staff is soldered or otherwise secured to the cylinder at the upper and lower heads of the latter as indicated at 22.

A lead-in wire 23 is connected to the staff and carried direct to the receiving circuit.

The invention having been described, what is claimed as new and useful is:

1. An antenna comprising a staff, a cylinder disposed adjacent one end of the stalf, the latter being coincident withthe axis of the cylinder, and outwardly directed radial fingers carried by the cylinder at an intermediate point in the height of the latter, the cylinder having a ring disposed in surrounding relation to it and the fingers being connected with said ring.

2. An antenna comprising a stafi, a cylinder disposed adjacent'one end of the staff, the latter being coincident with the axis of the cylinder, and outwardly directed radial fingers carried by the cylinder at an intermediate point in the height of the latter, the cylinder having a ring disposed in surrounding relation to it and the fingers being connected with said ring, certain of the fingers being extensions of diametrical rods extending through the cylindrical wall of the cyl-' inder and connected together and secured to said staif.

In testimony whereof he affixes his signature.
